Selective detection of D-lactulose by a porphyrin-based diboronic acid

摘要

Cis-5,15-bis[2-(dihydroxyboronyl)phenyl]-10,20-diphenylporphine (cis-DBPP) bearing two boronic acid groups in a 9 Angstrom distance has been synthesized. The absorption, fluorescence, and CD spectral changes were induced only by D-lactulose among 10 disaccharides tested herein. One can readily sense D-lactulose by the spectroscopic methods.
